cell specialisation in plants

Many cells are specialised and are adapted for their function. These modifications of the cell enable it to perform its task properly. Very abundant in cells that need a lot of energy (e.g. Some genes are only expressed in certain specialized cells, and it is these genes that are responsible cell specialization. Phloem cells are specialised to transport the products of photosynthesis around the plant. The neurons consist of the soma, dendrites, and axons. The axon terminates into a synaptic junction that transmits impulses from one neuron to the next with the help of chemicals called neurotransmitters. Dendrites are the cellular extensions that receive impulses, and axons are long cable-like projections that transmit the impulse to the next neurons. Cell differentiation Animals and plants produced by sexual reproduction begin life as a single cell – a fertilisedegg or zygote. Cell Specialisation – Animals The mid piece consists of centrioles and mitochondria wrapped around the axial filament of the flagellum.

In plants, the undifferentiated meristematic tissues are found in the apical tips and allow the plant to grow throughout its lifetime. Differentiation occurs numerous times during the development of a multicellular organism as it changes from a simple zygote to a complex system of tissues and cell types. ; Tubers are fleshy underground stems modified to store starch (e.g. Contains cell sap and when full pushes the cell membrane against the cell wall, providing support. Recaps basic plant cell structure and moves on to look at different ways plant cells and tissues may become adapted. Neurons can be up to one meter in length depending on where they are present. Cell specialization means that the cells in an organism are uniquely suited to reproduce. The centrioles after fertilization form the centrioles of the zygote, whereas the mitochondria provides energy for the movement of the flagellum (responsible for cell motility). Enzymes contained in adipose cells specialize in the hydrolysis of triglycerides in order to generate fatty acids and glycerol for physiological processes. The process of cell specialization – exactly how cells develop into their diverse forms – is complex. Contain chlorophyll, a green pigment that traps light for photosynthesis. One of the distinctive aspects of a plant cell is the presence of a cell wall outside the cell membrane. These features also differentiate plant cells from animal cells.
